Job Safety Assessment Form Chem-E-Car

2009 National Competition – Updated August 2009 University: University of Utah ChemE Car Vehicle Name: Louise JSA Author Contact Name: Derek Harris Author Email: [email protected] Faculty Supervisor: Kevin Whitty Supervisor Email: [email protected] Revision #: 2 Revision Date: August 7, 2009 Purpose of Experiment / Equipment: Briefly describe your Chem-E-Car’s design, intended mode for operation (source of power), intended mode for control (stopping), and major hazards and their control.

Describe your car’s design: Glacial acetic acid and sodium bicarbonate react in a pressure vessel built out of stainless steel. The reaction is: NaHCO3 + CH3COOH = NaCH3COO + CO2 + H2O. The resulting pressurized CO2 is fed through a pressure regulator to limit the driving pressure. A pressure relief valve on the pressure vessel is set to open at 10% higher than the maximum anticipated operating pressure. The CO2 gas flows through high pressure tubing to a pneumatic motor, which drives a chain-and-sprocket gearing system, which ultimately drives the rear axle and wheels of the car. The reaction is slightly endothermic.

Power source: Pressure generated by production of CO2 resulting from a chemical reaction of glacial acetic acid and sodium bicarbonate. Byproducts are water, carbon dioxide and solid precipitate. Carbon dioxide is the source of power for the car.

Stopping mechanism: The car will stop when the reaction is exhausted. We will vary the amount of the limiting reactant (acetic acid) to control the distance the car travels.

Hazards inherent in design: Glacial acetic acid has toxic exposure hazards. The gas generated is stored in a pressure vessel resulting in pressure hazards.

Safety measures: The pressure vessel will be hydrostatically tested according to the procedure in the rules. The vessel will be equipped with a pressure gauge and a relief device. The relief will be sized appropriately. All components exposed to pressure will be rated for the pressures expected. Management controls will be used to insure that the reactants are charged in the proper quantities. Appropriate PPE will used for car prep and chemical loading ( long pants, long sleeves, non-porous shoes, safety glasses, splash goggles, chemical gloves, and an apron). Chemical loading will be done in the chemical prep area. Proper chemical containment will be used in the prep area.

Expected Operating Conditions:

Temperature Pressure Normal: 68oF Normal: 225 psig Minimum: 60oF Minimum: 15 psig Maximum: 80oF Maximum: 280 psig

3. Design Basis for Maximum Operating Pressure

The spreadsheet on the next page calculates the pressure expected in the vehicle based on differing amounts of glacial acetic acid. The calculation assumes the reaction occurs stoichiometrically. It also assumes complete reaction and accounts for the liquid volume of the water product. The attached figure shows the pressure as a function of glacial acetic acid in ml. As expected, it is very close to a straight line – the volume occupied by the water volume does not have much of an effect. The pressure required depends on the performance of the Gast pneumatic motor. Specifications are provided in Section 5 of this report. We will regulate the pressure down to 20 psi, which is the lowest pressure that the motor will operate at. It is clear that this motor will produce a lot more torque than we need, even at the low pressures. At 20 psi the motor will operate at a speed from 1000 rpm and higher – we will need to provide a lot of gear reduction to the drive wheels. We will provide gear reduction adequate for the car to complete the maximum 100 ft course in 20 seconds. Assuming we operate at 20 psi and 1000 rpm, the air requirement is 5 cfm from the Gast motor spec. From the attached spreadsheet we will select a target gas volume of about 2 cubic feet, which will give us an operating time of about 24 seconds – more than enough time to complete the max. 100 ft course. The 2 cubic feet gas volume will require a pressure of about 290 psi. This will be our maximum operating pressure.

4. Design Basis for Estimating Relieving Mass Flow Rate The maximum operating pressure for the vehicle will be 290 psi. We will select a spring operated relief with a set pressure of 300 psig, which is below the 1.1 times the maximum operating pressure requirement. We could only find a spring operated relief that will operate at 350 psig. However, it is adjustable. We will adjust it an test with pressure to operate at 300 psig. The specifications for the relief device are shown in Section 5. We do not know the actual reaction rate. Our experience mixing these materials in an open beaker in the lab shows that the reaction takes seconds to complete. If the reaction occurs in 10 seconds and produces 2 cubic feet of gas (at the maximum operating pressure) then the gas evolution rate is

3 3(2 ft )(60 secs/min)/(10 secs) = 12 ft / min From the figure at the bottom of the specifications for the relief device (see Section 5), for a discharge rate of 12 scfm and a 300 psi set point, the maximum pressure will be about 320 psi. However, the pressure will never get that high. The pressure will be limited by the amount of reactant we place in the vessel. We will use a number of management control systems to insure that the vehicle is charged with the proper amount of reactants. This will include:

1. A minimum 2 person confirmation of the calculated quantities of material charged. 2. A red line will be place on the graduated cylinder to denote the maximum possible

amount of liquid glacial acetic acid that can be added. 3. The mass of sodium bicarbonate powder weighed will be confirmed by at least two

people. The weighing will be done in a beaker with a red mark indicating the maximum amount to charge.

4. Once the sodium bicarbonate is charged to vessel PV1, a red tag will be place on the outside of this vessel indicating that it has been charged.

5. Once the liquid glacial acetic acid has been added to vessel PV2, a red tag will be placed on the outside of this vessel indicating that it has been charged.

SX304/304L Technical Data

SummarySX 304 is the most versatile and the most widely used of all stainless steels. Its chemical composition,mechanical properties, weldability and corrosion/oxidation resistance provide the best all-roundperformance stainless steel at relatively low cost. It also has excellent low temperature properties andresponds well to hardening by cold working. If intergranular corrosion in the heat affected zone mayoccur, it is suggested that SX 304L be used.

Typical ApplicationsSX 304 is used in all industrial, commercial and domestic fields because of its good corrosion and heatresisting properties. Some applications include:

Tanks and containers for a large variety of liquids and solids.

Process equipment in the mining, chemical, cryogenic, food, dairy and pharmaceutical industries.

Thermal Processing

Annealing. Heat from 1010oC to 1120oC and cool rapidly in air or water. The best corrosionresistance is obtained when the final annealing is above 1070oC and cooling is rapid.

Stress relieving. SX304L can be stress relieved at 450-600oC for one hour with little danger of sensitisation. A lower stress relieving temperature of 400oC maximum must be used.

Hot working Initial forging and pressing: 1150 to 1260oC Finishing temperature: 900 to 925oC

All hotworking operations should be followed by annealing.

Note: Soaking times to ensure uniformity of temperature are longer for stainless steels than for carbonsteels - approximately 12 times.

Cold WorkingSX 304 / 304L being extremely tough and ductile, are readily fabricated by old working. Typicaloperations include bending, forming, deep drawing and upsetting.

9. Management System for Vehicle Modifications

All modifications to the vehicle after the initial design will be done to insure safety. All changes will be approved by the entire team prior to implementation. If the changes are major, then a complete safety review will be required, including participation by the faculty advisor. This would include any changes to the pressure vessel, relief system, maximum operating pressure, replacement of major equipment pieces, and reactant concentrations or quantities. If the changes are smaller in scope, the team itself can decide on the safety. The team will keep a log book of changes and will update the documentation to insure that the design package is current.

Symptoms may include coughing, sore throat, labored breathing, and chest pain. Ingestion: Large doses may produce abdominal pain, nausea, and vomiting.

Skin Contact: May cause irritation with redness and pain. Eye Contact: Contact may cause irritation, redness, and pain. Chronic Exposure: No information found. Aggravation of Pre-existing Conditions: No information found.

4. First Aid Measures Inhalation: Remove to fresh air. Get medical attention for any breathing difficulty. Ingestion: Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical advice. Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention if irritation develops. Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Get medical attention if irritation persists.

5. Fire Fighting Measures Fire: Autoignition temperature: 611C (1132F) As with most organic solids, fire is possible at elevated temperatures or by contact with an ignition source. Listed fire data is for the Anhydrous Material. Explosion: Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard.

Fire Extinguishing Media: Water spray, dry chemical, alcohol foam, or carbon dioxide. Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.

6. Accidental Release Measures Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Clean up spills in a manner that does not disperse dust into the air. Use non-sparking tools and equipment. Reduce airborne dust and prevent scattering by moistening with water. Pick up spill for recovery or disposal and place in a closed container. Small amounts of residue may be flushed to sewer with plenty of water.

7. Handling and Storage Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from any source of heat or ignition. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.

8. Exposure Controls/Personal Protection Airborne Exposure Limits: None established. Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.

Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. Skin Protection: Wear protective gloves and clean body-covering clothing. Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.

INGESTION EFFECTS:No adverse effects anticipated.

INHALATION EFFECTS:Carbon dioxide is the most powerful cerebral vasodilator known. Inhaling large concentrations causes rapidcirculatory insufficiency leading to coma and death. Asphyxiation is likely to occur before the effects of carbondioxide overexposure. Chronic, harmful effects are not known from repeated inhalation of low concentrations.Low concentrations of carbon dioxide cause increased respiration and headache.

Effects of oxygen deficiency resulting from simple asphyxiants may include: rapid breathing, diminished mentalalertness, impaired muscular coordination, faulty judgement, depression of all sensations, emotional instability,and fatigue. As asphyxiation progresses, nausea, vomiting, prostration, and loss of consciousness may result,eventually leading to convulsions, coma, and death.

Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimentalanimals.

7. Handling and Storage

Electrical Classification:Non-Hazardous

PRODUCT NAME: CARBON DIOXIDE, GAS

MSDS: G-8Revised: 6/7/96 Page 4 of 7

Dry carbon dioxide can be handled in most common structural materials. Moist carbon dioxide is generallycorrosive by its formation of carbonic acid. For applications with moist Carbon Dioxide, 316, 309 and 310stainless steels may be used as well as Hastelloy ® A, B, & C, and Monel ®. Ferrous Nickel alloys are slightlysusceptible to corrosion. At normal temperatures carbon dioxide is compatible with most plastics andelastomers.

Use only in well-ventilated areas. Carbon dioxide vapor is heavier than air and will accumulate in low areas.Valve protection caps must remain in place unless container is secured with valve outlet piped to use point. Donot drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a pressure reducingregulator when connecting cylinder to lower pressure (<3000 psig) piping or systems. Do not heat cylinder byany means to increase the discharge rate of product from the cylinder. Use a check valve or trap in thedischarge line to prevent hazardous back flow into the system.

Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily traffickedareas and emergency exits. Do not allow the temperature where cylinders are stored to exceed 125oF (52oC).Cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Full and emptycylinders should be segregated. Use a "first in-first out" inventory system to prevent full cylinders being storedfor excessive periods of time.

For additional storage recommendations, consult Compressed Gas Association’s Pamphlet P-1.

Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space suchas a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure.

Maximum use for potable water 100 mg/l.
